Hp Ux Ioscan

Hi I had to reboot my rx6660 (HP-UX 11.31) to see 4 new SAN LUNs. The 'ioscan -fnC disk' did not work. I always told proudly that 'HP-UX reboot is not required to configure new SAN LUNs' but it seems that has changed. Perhaps the 'rescan' must be done by 'scsimgr' command? Global Cell Number Format. The global cell number format is identical to the cells' HP-UX hardware path, as reported by the HP-UX ioscan command. In global format, each cell is given a single unique number that indicates the relative location of the cell in the entire server complex.

Use the cell and I/O chassis notation described in thissection when you manage, configure, and inquire about cells and I/O chassisusing the nPartition configuration commands.

Details are in the “Cell Specification Formats” and “I/O Specification Format” sections that follow.

Use either of the following two formats to specify cellswhen using the nPartition configuration commands: “Global Cell Number Format” or “Cell Hardware Location Format”.

• Global Cell Number Format. The global cell number format is identical to the cells' HP-UXhardware path, as reported by the HP-UX ioscan command.In global format, each cell is given a single unique number that indicatesthe relative location of the cell in the entire server complex.

• Cell Hardware Location Format. In cell hardware location format, each cell is identified using twonumbers that specify the cabinet and the cell slot with the cabinet wherethe cell resides: cabinet/slot.

  Superdome Cabinet1 Hardware Location Format	1/0	1/1	1/2	1/3	1/4	1/5	1/6	1/7

Both cell ID formats specify the location of a cell ina complex. For example, parstatus -c9 and parstatus-c1/1 specify the same cell.

Use the following I/O hardware location format when specifyingan I/O chassis to the nPartition configuration commands:

Hp-ux Ioscan

cabinet/bay/chassis

The cabinet, bay,and chassis fields specify the physical location ofthe I/O chassis. The values of these fields are as follows.

• cabinet

  specifies the cabinet number where the I/O chassis resides.

  On HP rp7405/rp7410, rp7420, rp7440, rx7620, rx7640, rp8400,rp8420, rp8440, rx8620, and rx8640 servers, the server cabinet number alwaysis 0.

  In HP rp8400, rp8420, rp8440, rx8620, and rx8640 complexesthe I/O Expansion cabinet, if present, is 8.

  On HP Superdome servers, the cabinet number can be:

  • 1 — the rightCompute cabinet, if present.

  • 9 — an I/O Expansioncabinet, if present.

• bay

  specifies the I/O bay (within a cabinet) where the I/Ochassis resides.

  On HP rp7405/rp7410, rp7420, rp7440, rx7620, rx7640, rp8400,rp8420, rp8440, rx8620, and rx8640 servers, the bay number always is 0.

  On HP Superdome servers, the bay number can be:

  • 0 — the frontbay of a Compute cabinet, or the bottom bay of an I/O Expansion cabinet.

  • 1 — the rearbay of a Compute cabinet, or the middle bay of an I/O Expansion cabinet.

• chassis

  specifies the I/O chassis (within a bay).

  On HP rp7405/rp7410, rp7420, rx7620, rp8400, rp8420, andrx8620 servers, the chassis number is:

  • 0 — Chassis 0,which connects to cell 0 and is the left chassis as viewed from the cabinetrear: the left eight PCI card slots.

  • 1 — Chassis 1,which connects to cell 1 and is the right chassis as viewed from the cabinetrear: the right eight PCI card slots.

  On HP Superdome servers, the chassis number is:

  • 1 — Chassis 1,the left chassis in the bay, as viewed when facing the bay/chassis.

  • 3 — Chassis 3,the right chassis in the bay, as viewed when facing the bay/chassis.

  In HP Superdome servers all chassis are 12-slot I/O chassis,both in Compute cabinets and in I/O Expansion cabinets.

The example below shows the parstatus commandlisting details about two different I/O chassis (cabinet 0/bay 0/chassis 1,and cabinet 0/bay 1/chassis 3).

Use the parstatus -I command to listall I/O chassis within a server complex, regardless of the chassis cell connectionsand nPartition assignments.

Use the HP-UX rad -q command or olrad-q command to list the currently available PCI I/O slots in thelocal nPartition and their status. The rad command is availablewith HP-UX B.11.11, and olrad is available with HP-UX B.11.23and HP-UX B.11.31.

In Example A-1, boththe parstatus and rad commands showdetails for various chassis and slots, including chassis 0/1/3.
